<p>On the one hand, regression. On the other, not incorrect codegen, just wrong path mapping in tracebacks. I'd say medium?</p>

<p>Yeah, medium sounds reasonable, it's not actively breaking the compile. By the way does anyone have any idea how common using -- remap-path-prefix is?</p>

<p>I use it quite some time, but medium is the best choice here because it doesn’t even influence the build process or the emitted code in a huge way. And I guess there aren’t much systems that will break with the „invalid“ paths in the binaries</p>
